AUTOMATIC CRADLE.

SPECIFICATION forming part of Letters Patent No. 511,127, dated December19, 1893. Application filed August I5, 1893. Serial No. 483,206. (Nomodel.) Patented in Italy June 2S, 1893, No. 34,348-

To au whom it may concern:

Be it known that I, GIAMBATTISTA DENEGRI, of San Pietro di Rovereto,Zoagli, near Chivari, in the Kingdom of Italy, have invented a new andImproved Automatic Cradle, (for which I have obtained a patent in theKingdom of Italy, No. 34,348, dated June 28, 1893,) of which thefollowing is a full and exact specification.

My invention relates toa cradle, the rocking movements of which areproduced by a clock-work actuated by a spring.

The objects of my invention are to produce such a cradle which can bemanufactured very cheaply, which will be noiseless and efficient inaction, and which will be simple and compact in construction'.

The particular features of novelty in my said improvement will be morefully hereinafter explained, and are illustrated in the accompanyingdrawings forming a part hereof, and to which attention is directed.

Figure 1 represents a side view of the improved cradle. Fig. 2 is alongitudinal section of the same. Figs. 3 and 4, are details, of theclock-Work.

In all of the above views corresponding parts are designated by the sameletters of reference.

The ordinary cradle A, with its feet B B forming an are of a circle, isplaced upon a wooden base C, which terminates at lthe rear end of thecradle in a wooden box D, containing the clock-work mechanism E, foractuating the cradle. Aplate F, directly beneath the bottom of thecradle A, forms a rigid connection between the two feet B B. Each ofthese feet is traversed by a guide pin G which is extended into anopening in the base C, where it is provided with a pin H, passingthrough the same. The guide pins G are placed so that, while preventingthe cradle from being displaced relatively to the base C, they enable itto make the necessary rocking movement. To the foot B is rigidly xed awooden shaft K which, extending to the rear,

is made for its main portion of wood, but the extremity which is fixedto the shaft K is made preferably of met-al and at the other extremityit is secured to the connecting rod M, by means of the leaf spring o,which does away with the necessity of a pivot. The upper end of the rodM engages with the crank portion of the drive shaft a, which in turningwill impart a reciprocating movement to the rods M and L, causing theshaft II, to partially rotate,

back and forth, and giving to the cradle the desired rocking motions aswill be understood.

The clock-work may be of the ordinary kind, but in order to render itsmovement as silent as possible I employ a governor of special form. Tothe extremity of the cranked shaft d is fixed a wooden disk b covered atits circumference with cloth c, Fig. d. This disk turns a wooden shaftd, to which are secured feathers e of fowls or other birds which extendradially so as to constitute the governor. At the part where the shaftCZ is in contact with the disk b it is provided with pins f, whichengage with the cloth c, and serve to insure the transmission of power.One end of the shaft g, engages, at i, in the frame-Work of theclock-work mechanism. The other end is carried by a supporting rod h,which is supported by a leaf spring la W'hen the pins f, are to engagewith the cloth covered surface `of the disk b, this leaf spring le, isto be held within a slotted support m, so as to be under tension, andeffect the proper engagement. When, however, it is necessary to allowthe clock-work mechanism to run down rapidly, the said leaf spring k, isto be shifted to a second slotted holder fa, so as to not be undertension, thereby throwing the pins f, out of engagement with the disk h.Upon the box D inclosing the mechanism is placed a handle P, and belowthe plate O a roller Q., which serve for enabling the automatic cradleto be easily moved about.

When the spring of the clock-work has once been wound up, or put undertension, it Will be suicient to push the cradle with the hand, in orderto give it the automatic rocking movement to start it, and in likemanner, if this movement is to be discontinued, it will be enough tostop the cradle for a incluent by hand.

Having now described and ascertained the nature of my said invention andin what man- IOC support h, and slotted supporting studs m and n, forsaid leaf spring 1c, said shaft g, carrying` pinsf, engaging with thecloth c, on the disk b, substantially as described.

In witness whereof I have signed this speci- 15 fcation in presence oftwo Witnesses.
